Sažetak
The fracture behavior of compact type (CT) specimens made of two different materials, steel AISI 304 and AISI 316L was numerically analyzed in this paper. The comparison of the two materials was based on the obtained values of J-integral, an important fracture mechanics parameter. The single specimen test method, commonly used in experimental determination of J-integral, was numerically modeled using finite element (FE) software. Consequently, a new numerical algorithm was developed for J-integral calculation on the basis of finite element (FE) analysis results. The paper sets out numerically obtained J-integral values presented as measure of crack driving force versus crack growth size (Δa) for three initial measures of a specimen crack size, being a/W = 0.25, 0.5, 0.75.
